Towards New Metrics for Urban Road Networks: Some Preliminary Evidence from Agent-Based Simulations
Road networks are complex entities, which are arranged hierarchically both in their structure (topology) and by speed. This property has a strong influence on their performance, both at an individual and collective level. Indeed, they intrinsically favour car use, especially for distant trips. In that sense, they may contribute actively to urban sprawl, a non desirable property of urban growth. In this chapter, we propose and explore a strategy aimed at regulating and even reversing such a “speed metric”. Using agents, we simulate road traffic on various road network structures and show how limited but well targeted actions can have a strong global impact on the system.
